    Magma
AI Thread Summary
The discussion centers on the concept of magma, a mathematical structure defined as a set with a binary operation. The focus is on commutative magmas with a unit element, which exhibit intriguing properties relevant to algebra and topology. The author explores a generalization of residue arithmetic, substituting linear spaces with various quotient spaces, leading to the discovery that the induced addition does not always form a group or monoid. A finite set, or magma, is derived from this discretization, suggesting a potential characterization of the quotient space. Updated resources, including software for calculating moduloids for different spaces, are available on the author's website.

Magma as the mathematical object may be too big to be dealt with.
However I found the magma which is commutative and has the unit element
has some interesting properties which might be applicable to algebra
and topology. For details, please visit;

For those wondering, like me:

A magma is simple a set with a binary operation into itself (ie something like an operation on equivalence classes of binary trees indexed by the underlying set). Examples of which are, groups, groupoids, monoids etc.

The link is to a nicely presented page, though I don't have time to read it to see what it is saying. Perhaps a summary? An abstract, here?

Thank you for your comment. My website is regarding a generalization of residue arithmetic, in short. You may imagine the residue space in the linear space. I substituted the linear space by some quotient spaces such as sphere, real projective plane, Klein bottle, etc. Then I found the addition induced in that space does not form group, or even monoid in some cases. By discretizing that space, a finite set - or magma - is obtained. I thought that magma may characterize the quotient space in a certain meaning.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
